About Us

Our Story

Heather Marsh (Ivory) grew up working in a small family-owned contracting business in southwest Ohio. After receiving her graduate degree, rising to an executive leadership role with a global engineering firm, and gaining national recognition in the tunneling industry, Heather became convinced there was a better way to deliver design and construction services. Driven by her entrepreneurial upbringing, she invested her life-savings and launched iTunnel and ITI Consulting in 2013.

In 2017, iTunnel and ITI Consulting became MarshWagner with the strategic addition of Fred Wagner.

After receiving his undergraduate degree in engineering and working a short stint as a designer, Fred Wagner decided that building complex mechanical systems was more fun than designing them. Fred spent much of his construction career in the field and rose to serve in executive roles in an industry where the lowest price wins the work. He spent the past 10 years embracing the growing demand for collaborative delivery of water infrastructure projects before joining Heather in 2017 to build a more collaborative, value-driven platform for delivering specialized design and construction services.

Our Vision

MarshWagner was founded on a shared vision and strong desire to create a stimulating work environment and culture that inspires and empowers an extremely talented and diverse group of design and construction professionals to produce better project outcomes.
